Default motor / ESC timing

Need some advise on timing, I think....

I have a brushless motor that the specs tell me should draw 20A and produce 200W. This motor is installed on a HK 250, with a 40A ESC. during testing I have placed my Watt's up meter and found something else.

Under 1/2 throttle is am drawing 56A, and developing 540w, and the motor and ESC is HOT!

The spec's on the motor are:

Turgeny E500, 6T, 4000Kv, with 11 tooth pinion

I have checked all rotos for binding and have found NO defects in the Heli.

The ESC is set up for the following:

break off
Li PO battery
cut off mode - cut/off
start mode - super soft
timing - high

Anyone got any suggestions?

Would timing issues cause over heating and high current draw?
